Ubuntu “Feisty Fawn” 7.04 has two more months before its planned release on April 19th. Herd 4, the fourth alpha release is another milestone on the road to final release. Herd 4 is the first herd release after Feature Freeze, meaning testing is very much needed and each alpha/beta release from now on will require extensive testing to guarantee rock-solid stability in the final version.
